4.2 We use source netcat to run on port 44444, verity port listen status

LISTEN status indicates Source started properly

netstat -na|grep 44444
tcp 0 0 ::ffff:127.0.0.1:44444 :::* LISTEN

4.3 Now do the telnet test to verify source/channel/sink i.e when you telnet and type some message, it should pass through memory channel to the hdfs and create a file there as it’s configured as sink.

Terminal 1:

telnet localhost 44444
Trying 127.0.0.1…
Connected to localhost.
